Hi - my nephew has Philadelphia positive ALL - he is 4. He has been on chemo for 7 days, on the Ph+ chemo for 1 day and his white cell count at diagnosis was 84 - they dropped to 0.6 but now are back up to 1.9 (despite being on chemo for the last 6 days) - his hemogoblin and platelets also dropped rapidly and the doctors said they wanted to see a steady number but did not and were concerned that he was not responding well to chemo. What would make his cell count go back up, and what does that mean for remission possibility - they won't tell us. He has about 7 days of induction left.
